Description of problem: I have just upgraded to Fedora 8 and have an ATI Radeon 7500 based video card. Sometimes during boot, when the video switches from text display mode to graphical during Fedora initialization, the screen will blank from the text mode but never enter the graphical mode. It stays blank and the monitor no longer receives a video signal. The OS is still initializing (I can see the disk activity). Problem may also happen switching to the GDM login screen either after a Fedora boot-up or logging out from a user session: the screen will go blank, expecting to show the login screen, but no signal to the monitor. If I use Ctrl-Alt-F1 to attempt to go to the command line mode, the monitor remains blank with no signal. In fact, no matter what I press or any mouse motion does not change this state. However, after pressing Ctrl-Alt-F1 I can reboot the system with Ctrl-Alt-Del. Rebooting the system will sometimes recover everything, but will sometimes hit the problem as first described. I was seeing something like this in Fedora Core 5 (my prior version) but had only recently installed the video card so I don't have a lot of examples of it happening there. Version-Release number of selected component (if applicable): (Just let me know what components you want versions of and how to obtain the info and I will provide it.) How reproducible: This happens regularly but hard to tell percentage. For now I'd have to say about 50% of the time when logging out or system initialization. Steps to Reproduce: 1. Boot Fedora 8 2. Watch screen attempt to go to graphic mode during init 3. Watch screen go blank (while attempting graphic mode) and remain blank with no signal OR 1. After successful boot of Fedora 8 login and use system 2. Log out and watch screen go blank before login screen appears 3. Note that login screen does not appear, but screen remains blank with no signal In all cases, recovery is done by waiting for system to be stable, pressing Ctrl-Alt-F1 to get to a command line mode (screen remains blank with no signal), then pressing Ctrl-Alt-Del to reboot.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.

Created attachment 268081 [details] Xorg log file (after removing xorg.conf and doing system reboot) I removed (actually renamed) /etc/X11/xorg.conf then rebooted the system. After initialization of Fedora 8, the screen went blank in preparation for showing a login screen, but the video signal just went away and didn't come back. No login screen appeared, just blank. I had to recover by Ctrl-Alt-F1, then Ctrl-Alt-Del (all with blank screen). System rebooted and gave me a login screen. I will post that Xorg log file (successful second boot) as well.

OK.... duh.... I was noticing in all the files I captured that X was using the right radeon driver, but a generic monitor type. Evidently the monitor type is not detected. I set the monitor type specifically using the Gnome display config tool (which updated xorg.conf accordingly with the monitor type) and the problem has so far not recurred. So please stand by. If you don't hear from me with another post, assume that the problem is fixed by setting the monitor type specifically.
OK, well problem is still there. I had several successful successive logouts/logins so I thought the problem had gone away after setting monitor type. Maybe it happens less frequently now? Not sure. Time will tell. I have attached another Xorg log file for the last failure after bootup (system booted up but blank screen, no video signal for login or any Ctrl-Alt-Fx choice).

It's been two days since I've had an "event" and just had another. In this case, the monitor (actually, the display card) would not "wake up" to my login screen when I moved the mouse. Screen remained blank with no signal. I was, however, able to use the keyboard Ctrl-Alt-F1 and then Ctrl-Alt-Del to recover (note: screen remained blank after Ctrl-Alt-F1). When I rebooted, I immediately went to single user mode and saved Xorg.0.log (as Xorg.0.log-reboot-after-blank) and Xorg.0.log.old (as Xorg.0.log-eve-of-blank).

Common thread in logs after failure is the line: (II) AIGLX: Suspending AIGLX clients for VT switch This line does not appear in logs in success cases. At least it seems this way. Not sure exactly when the log gets written.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
